SHOVEL 0R CRANE.

Application mea August 14) 1925. seriai No. 50,217.

This invention relates to shovels or cranes and particularly to shovels or cranes mounted on tractors, trucks or other vehicles.

The chiefobject of the invention is to provide in` an apparatus 1 of the class described, a' device for elevating the vehicle above the ground to convert it into a full revolving platform for a shovel or crane and also to provide means for rotating' the platform driven by the power driving unit of the vehicle.

The foregoing and other objects are o'btained by the construction illustrated in the accompanying drawings and described below. '1t is understood that the invention is not limited to the specific embodiment thereof shown and described. I

Of the accompanying drawings:

FigureI 1 is a side elevation, partly in sec-- tion, of a tractor driven shovel embodying the invention, the shovel being shown in operative position for excavating.

' Figure 2 is a plan thereof;

Figure' 3is a detail elevation of the elevator mechanism control means; andA Figure 4 is a section therethrough on line 4 4 of Figure 3.

Referring to the drawings, 10 represents, generally, the chassis of a suitable vehicle, such as a tractor, mounted on wheels 1l, 11 and 12, 12 and driven in the customary manner by a motor 13, a suitable steering mechanism for controlling front wheels 12 being illustrated at 14. y

To carry out the present invention, the

chassis 10 is provided with a central upstanding' lcylinder 15in which is slidably mounted a vertical, hollow, cylindrical stud' 216 having on its lower end a base 17 which fis adapted to support the entire vehicle 10 off the ground in. the manner shown in full lines .in Figure 1, but which, during the travel of vehicle 10, may be suspended above 'the ground beneath chassis 10 as illus-` trated in dotted lines in Figure 1. Stud 16 also provides a central pin about which ve hicle 10 may rotate when in use as a shovel or crane.

The vehicle elevating mechanism includes a screw-18 journaled in "a bearing -19 in the top of the central cylinder 15 and extending downwardly therein and threaded through a head 20 secured on the top of stud, 16. Suitable braces 15, 15a may be employed for strengthening the cylinder 15 so that.

lrevolving of the shovel.

For operating screw 18 to raise or lower vehicle 10, the screw 4has secured on the topthereof a bevel gear 21 meshing with bevel gears 22 and 23 rotatable on a cross-shaft 24 journaled in bearing bracketsr 25, 25 Supported on the top of cylinder 15, gear 22 or 23 being adapted to be clutched onto shaft 24 by means of a cone clutch 26 or 27 shiftable by means of a collar 28 keyed or splined onto shaft 24 and operable by a yoke 29 secured on a rod 30 slidable on brackets 25 and'adapted to be handbperatcd by a bell crank lever 31 to which is connected a rod 32 in turn connected to a hand lever 33.

Shaft 24 may be driven by'a sprocket 34 over which is trained a chain 35vdriven by a sprocket 36 on a hoist operating shaft 37 which may be driven by a gear 38 thereon meshed with a pinion 39 driven by a pulley 40. Pulley 40 may be driven by a belt 41 trainedover a pulley 42 driven in any suitable manner by motor`13. y

In order that the elevation or lowering of the stud 16. may automatically be limited so as tok prevent destruction of the device" by improper manipulation of lever 33, there s,

is arranged so as to slide on cylinder 15,

and engaging in a circumferential groove 46 t in head 20 whereby sleeve 43 will slide on cylinder 15 with said head but-will be permitted to rotate relatively thereto during Sleeve 43 has connected thereto an arm 47 through the end ofwhich is arranged' to slide a rod 48 connected by a bell crank lever49 to rod 30 so as to reciprocate the latter as will be eX- plained. On rod 48 are collars 48al Yand 481,

the former being positioned so as to be engaged by arm 47 to automatically throw out clutch 27 when the desired elevation of the chassis'l() has been reached, and the latter beingso positioned asjto be engaged by arm `47 to throw out clutch 26 when base 17 `has been drawn upwardly sufficiently under chassis 10. 1 l

The revolution of the vehicle 10 on Stud 16 is effected by means of a ring gear 49 rotatably` mounted on the under side of chassis 10 and keyed or splined onto stud 15,V as indicated at 49a, so as to be slidable thereon. Meshed with ring gear 49 is a pinion 50 secured on a shaft 51 journaled on chassis 10 and having a bevel gear 52 fixed thereon and meshed with bevel gears 53 and a' journaled on a shaft` 55. Shaft 55 is journaled on chassis and -has keyed or sPlined theljeon shiftable clutches'56 and'56" operable by collar 57 for clutching either 5 gear 53 or 54 to the shaft to drive pinion 50 10 61 in turn connected to-a lever 621 in either direction. Collar 57 is-operable by means of a yoke 58 on a reciprocable rod 459 operable by hand by means of a bell crank lever 60, to which is connected a rod The constructionl described, above illustrates thel manner in which'the vehicle 10 may be elevated above the groundand revolved into any position while so. elevated.

" The vehicle mayicarry a hoisting device: such as a crane or a shovel as shown., The

followin description will rieiiy set forth I the provisin of a shovel on said vehicle.A

' On the-forward end of chassis 10 is supan ported a boom63 supported in an upwardly a ca y boom -63 and extending.l 4about a baleS `i attached to scoop 66 and over a-sheavei70fon 'the' end of boom 63 toca hoisting drum -7-1 inclined osition by therods 64, 64. and having slida ly mounted thereon in any suitable 'manner a dipperjstick' carrying a scoop O eration of stick 65 can .be ei'ected'by Ible 67 connected at 68 to the end yof v juournaled oni-shaft l-f-'jand arranged to 'be v and 56% clutched thereto by being shifted by'means (not shown) finto engagement' witha cone 72 fixed on shaft 37. A cable 73 is also connected to dipper stick'65'for control 35 thereof and is.` passed over a sheave` flion one lbrace 15a to a drum 71 in' -all respects similar to drum .7l and operable by suitable means (not shown).

Movement of stick bycables 67 and 73 ma `be controlled infany suitable way, as by.ca les 75 and 76,connected t'o opposite ends of stick 65 and'reversely wound upon a drum 7 7 `journaled on boom 63 and about which is a brake band 78 normallyprevnting i rotation of drum 77 by action of a spring 79,Qbut adapted -to be released by a cable 80 connected thereto and to an operating lever 8l on chassis 10.

The operation' of the device will beunderi' stood, from the fore-going description.

Briefly, it consists in transporting theshovel" or crane from place to place bydriving vehicle 10 in the usual manner. When at the operating location, clutch 27 will be engagedand screw 18 driven iirst to lower base 17 onto the ground and then to elevate chassis 10 on stud 16 to the position shown in Figure 1, the clutch being automatically disengaged, as willbe understood.

The shovel or crane may now be operated in the customary manner, revolving of the chassis to and fro or completel around to any angular position on' stud 1 6 eing effected by proper-macnipulationV of clutches 56 It will appear from the foregoing that the present inventor has devised a vehicle, i. e.,
